Again, you’re taking the English language and your level of education for granted. Also, the ability to have someone home for the day for the kids. I suspect you don’t quite realize how extreme some of these immigrant family situations are.
My husband and I have been working with the poorest of the poorest immigrants in the U.S. for 6 years.
Those families that afterschool their kids learn. Those that don’t, don’t learn. This is true for both immigrant and Anglo kids.
The immigrant families who afterschool look for and find support among family, friends, and neighbors even when they are illiterate (even in their own language) themselves.
